STI (Sexually Transmitted Infection) and STD (Sexually Transmitted Disease) — they sound similar and are often used interchangeably, but they’re not exactly the same. At Test Smartly Labs, we help individuals throughout Kansas City and surrounding areas understand their health risks with fast, private, and affordable STD testing.
Understanding the difference between STI and STD can help you make more informed decisions about your sexual health. Here’s what you need to know — and why routine testing matters, even if you feel healthy.
STI vs STD: What’s the Real Difference?
What Is an STI?
An STI refers to an infection that is transmitted through sexual contact. It means the virus, bacteria, or parasite is present in the body, but may not have caused any noticeable symptoms or health complications yet. A person can carry an STI and have no idea they are infected — which is why routine testing is essential, even for those who feel perfectly fine.
What Is an STD?
An STD occurs when an infection develops into disease — meaning the virus or bacteria has caused disruption to the normal functioning of the body. This typically includes visible symptoms or long-term damage such as infertility, chronic pain, or neurological issues.
In simple terms:
| STI | STD |
|---|---|
| Infection has entered the body, may have no symptoms | Infection has progressed, causing symptoms or damage |
| May or may not develop into disease | Always the result of an untreated or advanced infection |
| Easier to treat if caught early | May require ongoing treatment or management |
Why This Distinction Matters for Testing
You can be a carrier of an STI and not know it — but still pass it to a partner. According to the CDC, up to 70% of women with chlamydia are asymptomatic, yet still infectious.
Getting tested early — before symptoms develop — can stop the infection in its tracks, prevent complications, and protect your current or future partners.
Real-World Example: HPV
-
A person contracts HPV (human papillomavirus) — they now have an STI.
-
Over time, that infection leads to cervical cancer — now it’s an STD.
Other Examples:
-
Chlamydia progressing to Pelvic Inflammatory Disease (PID)
-
HIV infection developing into AIDS
-
Gonorrhea causing infertility or chronic pelvic pain
STD Statistics in the U.S. (Why Testing Is Critical)
The numbers don’t lie — the STI/STD crisis is real, and growing:
-
Nearly 20 million new STDs occur each year in the U.S.
-
50% are in people aged 15–24, yet only 12% in that age group get tested
-
HPV affects 42% of men and 40% of women aged 18–59
-
1 in 8 adults (14–49) has genital herpes
-
Gonorrhea cases surged 75% between 2009 and 2017
-
Chlamydia remains the most reported STD, with 1.5 million+ cases in 2015
-
39,782 new HIV diagnoses occurred in 2016 — with 15% unaware they’re infected
Get tested. Know your status. Protect your health.
Why Testing Is Empowering — Not Shameful
A major reason for shifting the terminology from “STD” to “STI” is to reduce stigma. The word “disease” often triggers shame or fear — leading many people to avoid testing altogether. But the truth is:
-
Most STIs are curable with a round of antibiotics
-
Viral infections like herpes or HIV are manageable with medication
-
The earlier you test, the better your outcome

Do You Need A List Of My Medications For A Drug Test?
Per protocol, the lab techs are not allowed to receive or ask for your medications. A medical review officer or MRO, a licensed physician who specializes in toxicology, will call you and ask for your medications and your physician’s phone number if it’s detected in your sample during testing. The MRO will then call your physician to verify your medications.
Related Information
Understanding STI vs STD
STI stands for “Sexually Transmitted Infection” and STD stands for “Sexually Transmitted Disease”. These two terms sound similar and the difference between them can be confusing. One of the reasons for this is that up to a certain point these two terms were synonymous and were used interchangeably. But now there is a technical difference between these terms which has been acknowledged by the medical community and can no longer be used synonymously.
Privacy Matters for STI/STD Testing at Test Smartly Labs
While all health-related matters deserve the utmost privacy and confidentiality, some types of blood tests and lab work need even more. When it comes to STI or STD testing, you do not want to have any small chance of anyone you know finding out about your risks or diagnoses. Of course, if you go to your doctor’s office or even a public clinic, the HIPAA rules require everyone involved to keep your information private and secure. However, you may still have some doubts troubling your mind.
